API
Read-only JSON over the same records the pages render, with sources, verification dates and confidence levels in every response. Bounded and rate-limited by design; please use it rather than scraping the HTML.
Endpoints
Representations
Every organization page has three forms generated from one record: HTML at /organizations/{slug}, JSON at /organizations/{slug}.json and Markdown at /organizations/{slug}.md. AI systems should start at /llms.txt.
Limits
Anonymous use is limited to 30 requests a minute per address; listings are capped at 20 rows and 100 total. Keys with higher daily quotas are available for research and product use by arrangement — write to us and say what you are building. There is no endpoint that returns the whole database, and the Terms of Use prohibit systematic extraction and reproduction.
The obligation that comes with the data
Every requirement and fee row carries verified_on, confidence and source_url. If you republish a figure, carry those fields with it. A threshold without its date is not information, and presenting a reported figure as an official one misrepresents both the organization and us. Attribution — a link to the canonical page — is required by the terms for systematic use.
Responses carry Cache-Control: public, max-age=600 and Access-Control-Allow-Origin: *.
